beta-ray-generator

German Architect Andre Broessel believes he has a solution that can “squeeze more juice out of the sun”, even during the night hours and in low-light regions. His company Rawlemon has created a spherical sun power generator prototype called the beta.ray. His technology will combine spherical geometry principles with a dual axis tracking system, allowing […]

Solar Energy News -- ScienceDaily

Solar Energy Information. Read the latest news and techniques for efficient solar photovoltaic power, new solar energy systems and more.

In perovskite solar cells, charge carriers are mainly lost through recombination occurring at interface defect sites. In contrast, recombination at defect sites within the perovskite layer does not limit the performance of the solar cells at present. Teams from the University of Potsdam and the Helmholtz-Zentrum Berlin (HZB) were able to reach this interesting conclusion through extremely accurate quantitative measurements on 1 cm2 perovskite cells using photoluminescence.

Researchers developed a technique for coating Zinc related oxide (ZnOx, ZnOHx) simply by depositing the films in a solution process using the Metal Organic Decomposition method at ambient temperature and pressure without heating. They also demonstrated that their thin films produced by this technique were useful as buffer layers for OPV cells and that the films achieved a power conversion efficiency equivalent to that of ZnO thin films produced by conventional methods involving sintering.

Researchers have shown how long-term weather patterns affect wind and solar renewable energy technologies across Europe. The work suggests that despite the unpredictable nature of wind and solar energy, the European power system can comfortably generate at least 35 percent of its electricity using these renewables alone without major impacts on prices or system stability.

Hawaii is famously reliant on imported fossil fuels, for both electricity and transportation. But that’s changing rapidly as the state invests heavily in renewables. Two new bills are now pending in the Hawaii legislature that would codify the 100 percent renewables goal statewide, up from the current mandate of 40 percent by 2030. HB 623 would require...
